Currently, I am a member of the NASA Ames Intelligent Robotics Group, where I have been working on Astrobee, a robot that will autonomously fly inside the International Space Station. I have also been working on mapping floods automatically from satellite imagery.

Previously, I was a Ph.D. student in the Robotics Institute at Carnegie Mellon University, where I was advised by Manuela Veloso. While there I developed the CoBot robots together with Joydeep Biswas and Stephanie Rosenthal. The CoBots have traveled over a thousand miles autonomously, performing tasks for users in a multi-story office building. My Ph.D. thesis focused on scheduling these robots to perform pickup and delivery tasks, with transferring items between robots. At CMU, I also competed at RoboCup soccer in the Standard Platform League with the NAO robots.
